Based on the amount earned by Justin per hour, and the overtime work rate, Justin's gross pay for the week is $764.50

First, find the amount that Justin earns from Rite Aid Pharmacy for his regular work:

= Number of hours in regular week x Pay per week

= 40 x 13.9

= $556

The overtime hours was:

= 50 - 40

= 10 hours

The overtime pay is:

= 10 x 13.9 x 1.5

= $208.50

The total gross pay for the week is:

The probability that it is a female with long hair is 0.75 .

Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability generally refers to the degree to which something is likely to occur. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty. Every event's probability in a sample space is one.

the likelihood of an occurrence, E is

P(E) = The proportion of positive outcomes to all outcomes.

In probability, an event is said to be independent if it is completely unaffected by the occurrence of any other event, and it is considered to be dependent if it is affected by other occurrences.

Using the literature and formulas mentioned above, we have:

Let F stand for the circumstance that the student is a female and L for the circumstance that the student has long hair.

In this illustration, the probability are as follows:

P(F) = 0.60; P(L) = 0.50

P(F AND L) = 0.45 and P(L|F) = 0.75 as a result.

As a result, there is a 0.75 percent chance that a randomly chosen student has long hair.

Answer:

Tile a rectangle with unit squares. It is 8 unit squares long and 7 unit squares wide. Each unit square represents one square inch.

Step-by-step explanation:

The time taken to create a 2-foot by 4-foot pattern drive is 38.4 minutes.

A unit rate means a rate for one of something.

It is written as a ratio with a denominator of one.

We have,

A rectangle tile area = 3-inch by 5-inch

Area = 15 inches

Time taken to position 15 inches tile = 6 minutes.

We can write as,

15 inches = 6 minutes _____(1)

We have a 2-foot by 4-foot pattern drive.

Area = 8 feet

We know that,

1 foot = 12 inches

Multiply both sides by 8.

8 feet = 8 x 12 inches

8 feet = 96 inches _______(2)

Now,

From (1) and (2) we get,

15 inches = 6 minutes

Multiply 96/15 on both sides we get,

96/15 x 15 inches = 96/15 x 6 minutes

96 inches = 38.4 minutes

Thus the time taken to create a 2-foot by 4-foot pattern drive is 38.4 minutes.

The absolute function f(x) = 4x+5 as a piecewise-defined function is:

f(x) = { -4x-5   ,   x<-5/4

           4x+5   ,   x ≥-5/4 }

Given, the absolute function  f(x) = 4x+5

The fundamental tenet of piecewise linear regression is that we should construct the regression function in "pieces" if the data exhibit various linear trends over various parts of the data. The components may or may not be joined.

when  4x+5 < 0

4x < -5

x < -5/4

f(x) = -(4x+5) = -4x-5

when 4x+5 ≥ 0

4x ≥ -5

x ≥ -5/4

f(x) = 4x+5

so f(x) =  { -4x-5   ,   x<-5/4

                4x+5   ,   x ≥-5/4 }

since, I x I =  { -x   ,   x<0

                        x    ,   x ≥0}

Therefore, we get the required piecewise-defined function with linear parts.

Answer:

4.25c + 3.5p = 36.50

c + 6 = p

c = candies and p = pretzels

Step-by-step explanation:

So for the first equation, the prices will be the coefficients of each variable, since for each candy/pretzel it will be that price. We also know that both of these prices together equal 36.50, so that will be on the other side of the equal sign. So the equation representing this info is 4.25c + 3.5p = 36.50

And for the second equation I saw that Mason bought 6 more pretzels than candies. So no matter what number the candies is, the pretzels should always be 6 more than the candies. So the equation representing this information is c + 6 = p

Lastly I just defined the variables that I used to right the system. That is all! Hope this helps you this should be correct :)

The the coordinates of endpoint J on line segment JL with a midpoint of (-2, 6) is ( -3,15 ).

A midpoint is simply a point that divides a line segment into two equal halves.

The midpoint formula is expressed as;

M = ( (x₁+x₂)/2, (y₁+y₂)/2

Given the data in the question;

Midpoint K(-2, 6)

Point L(-1, -3).

Point J

To determine the coordinate of point J, plug the given points into the midpoint formula above and simplify.

First, we get the x-coordinate of point J

x = (x₁+x₂)/2

2x = x₁ + x₂

2( -2 ) = x₁ + ( -1 )

-4 = x₁ - 1

x₁ = -4 + 1

x₁ = -3

Next, we get the y-coordinate of point J

y = (y₁+y₂)/2

2y = y₁ + y₂

2(6) = y₁ + (-3)

12 = y₁ - 3

y₁ = 12 + 3

y₁ = 15

Therefore, the coordinates (x₁,y₁) of the endpoint point J is ( -3,15).

There are diffrerent ways to use the word

The average in general is the same as the term average in mathematics.

Arithmetic mean or average can be obtained by adding all the given values and then dividing the total sum by the number of values.

The meaning of average, in general, is quite similar to average in maths.

Answer:

x = 15

z = 64

Step-by-step explanation:

Lets make an equation -

(14x - 94) + z = 8x - 4 +z

Both sides are parallel to each other, and therefore the sum is also 180.

Then we solve it -

14x - 8x - 94 + z = -4 + z

Bring the z on the other side to eliminate it.

6x - 94 = - 4

Add 94 on both sides

6x = 90

Divide 6 on both sides and you get x = 15

Substitute x into 8x -4 + z = 180

8*15 - 4 + z = 180

120 - 4 + z = 180

116 + z = 180

Subtract 116 on both sides.

z = 64.

Answer:

Step-by-step explanation:

1. To find the value of x, you'll need to set 14x-94 equal to 8x-4. We do this since the two angels are congruent, and congruent angles are equal to each other:

[tex]14x-94=8x-4[/tex]

You'll then solve for x by isolating the x value.

[tex]14x-8x=94-4[/tex]

[tex]6x=90[/tex]

[tex]x=\frac{90}{6}[/tex]

[tex]x=15[/tex]

2. To find z I would plug in the x value to one of the equations, such as 8x-4, in order to find the measure of that angle:

[tex]8(15)-4\\=116[/tex]

We now know that 14x-94 and 8x-4 are equal to 116. To find z you'll add the angle opposite to it, the blank angle since they are congruent. Now you'll add all the angles together and set the equation equal to 360:

[tex]z+z+116+116=360\\2z+232=360\\2z=(360-232)\\2z=128\\\frac{2z}{2} =\frac{128}{2} \\z=64[/tex]

Your final answers are x=15 and z=64, hope this helps!

The number which is at a distance of 23 unit from 12 on a number line is 11.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used to determine the difference between two numbers such as 23 and 12. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.

Now, we can determine the distance as follows:

The equation of the line in the point-slope form is y + 3 = 1/2(x - 5)

From the question, we are to determine the equation of the given line in point-slope form

First, we will determine the slope of the line

Using the points (1, -5) and (3, -4)

From the formula,

Slope = (y₂ - y₁) / (x₂ - x₁)

Slope = (-4 - -5) / (3 - 1)

Slope = ( -4 + 5) / 2

Slope = 1/2

Now,

For the point-slope form of the line

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

Where m is the slope

The given point is (5, -3)

Thus,

The point-slope form of the line is
